PQWT-TC300 Series geophysical prospecting instrument: the use of natural electric field source as a working farm, with resistivity contrasts underground rocks and minerals or groundwater, based on measuring the natural electric field on the surface of the N different frequency electric field component, according to their different variation to study Abnormal changes in geological bodies produce, reaching solve geological problems one electrical prospecting methods. According to this theory the design and production of equipment called potential frequency of detecting instrument, referred to natural selected frequency electric field instrument or instruments for geological exploration work. The instrument is the use of natural earth field source without going through artificial field that is omitted clumsy power supply system in order to achieve the simple, lightweight instrument.
After data collection by the unique built-in computing functions, the instrument can automatically draw curve graph and profile map with one button, according to the profile map, you can clearly understand the geological structure and quickly determine the location of ore body (seam), hollow (cave), water (aquifer) etc.
1. High Measurement Speed and high efficiency
Complete more than 8000 meters profile measurement in one day to realize geological abnormality in different depth, the prospecting speed and efficiency is improved about 10 times more than traditional resistivity method.
2. Convenient to Carry
Without heavy power supply, it uses low frequency signals in earth natural electric field as signal source, and the complete set weight is less than 2kgs so easy to carry.
3. Simple operation
Equipment is automatically controlled by micro PC. You can learn its operation in 10 minutes. It will take 10 minutes for persons without prospecting experience to finish training.
4. Good performance and high Accuracy.
The resolution of measurement is up to 0.001mV, and precision is ±2%. It gains high stability and abnormity curves matching with that of traditional geo-electrical equipment in lots of field survey.
5. Strong Anti-interference Ability
It has advanced anti-jamming technology and multiple anti-jamming designs. You can observe abnormity curves result with good repetition even in weak signal area, city, high electric jamming area and working area with other exterior interference via frequency selector and digital processing.
6. The unique feature of Automatic mapping
This instrument can automatically form curve graph and profile map with one button after completed recording data, no need transfer the data to computer for drawing mapping.
